So this is the second time I've left M43 for another system, only to be disappointed with other systems and come back. The first time I though I could go all Nikon and combine my Nikon FF kit with the Nikon 1 mirrorless system. That didn't work! More recently I tried going Sony for mirrorless, but I realized the investment into their FF system was way expensive on the lens side and the APS-C E-mount lenses (while having a few jewels), lacked the variety, depth, and cheaper cost of M43. I'm glad Olympus released the E-M5 II, that camera literally killed my interest in bigger sensors due to the high resolution mode. I do a lot of nighttime still exposures, and that camera was exactly what I was looking for. I also own a Nikon D800 for my work, but trying to lug that body with a larger sized tripod (to handle the weight of that body), is a real pain. The E-M5 II and a lightweight carbon fiber tripod are great for keeping the weight down, while still churning out hi-res imagery! While Micro Four-Thirds isn't the best in any one category, it sure does a lot of things well! Anybody else switched systems only to come back?
